Olivia is conducting a study on whether sleep deprivation increases stress levels. she plans to observe and measure levels of stress based on whether the subjects were assigned to the deprived or non-deprived sleep conditions. in this experiment, the stress level is the:

Dependent variable

Explanation:

In research, we have two different types of variables:

In this example, Olivia is conducting a study on whether sleep deprivation increases stress levels. She is going to observe and MEASURE levels of stress based on the group (deprived or non-deprived sleep) the subjects were assigned to. We can see that the stress will be affected by the conditions of sleep the subjects are assigned to and this is the variable that will be measured. Therefore, the stress level is the dependent variable

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !
